For those who don't know, the town has a mine fire that's been burning for more than 40 years. The town is located in the heart of the Pennsylvania Anthracite Coal Region.
This coal is the longest burning, most sought after coal in the world.
The fire was said to have begun when a fire in the town dump jumped to an exposed coal vein. The rest is all history.

Mine fire
This was a world where no human could live,
hotter than the planet Mercury, its atmosphere as poisonous as Saturn's.
At the heart of the fire, temperatures easily exceeded 1,000 degrees Fahrenheit.
Lethal clouds of carbon monoxide and other gases swirled through the rock chambers.

Centralia is a borough and ghost town in Columbia County, Pennsylvania, United States. Its population has dwindled from over 1,000 residents in 1981 to 12 in 2005, 9 in 2007, and 10 in 2010,
as a result of a mine fire burning beneath the borough since 1962 Centralia is one of the least-populated municipalities in Pennsylvania.
Centralia is part of the Bloomsburg-Berwick micropolitan area. The borough is completely surrounded by Conyngham Township.
All properties in the borough were claimed under eminent domain by the Commonwealth of Pennsylvania in 1992 (and all buildings therein were condemned),
and Centralia's ZIP code was revoked by the Post Office in 2002. However, a few residents continue to reside there in spite of the failure of a lawsuit to reverse the eminent domain claim.
